Description

  The present invention relates to a mounting aid for a pen-type syringe. More specifically, the present invention relates to a pen-type syringe mounting aid that can accurately attach a syringe needle to a pen-type cartridge in any situation.

  Conventionally, blood sugar level is adjusted to treat diabetes, but insulin is not secreted in the body in type I diabetes with advanced diabetes, so it is necessary to administer insulin regularly. Performed exclusively by subcutaneous injection. And since the injection of insulin is performed several times a day, it is necessary to be able to easily inject when the patient himself / herself is necessary at home or at work, and therefore, a pen-type syringe has been devised.

  The pen-type syringe can accurately set the amount of insulin to be injected into the body, can be simply injected, and is easy to carry. There are two types of pen-type injectors, a cartridge type and a disposable type. In the cartridge type pen-type syringe, a cap-shaped injection needle built into the needle case is screwed and attached to the tip of the pen-type cartridge containing a predetermined amount of insulin preparation determined by a diabetic patient, Thereafter, the insulin preparation is injected into the body by inserting a needle into the treatment site. Then, after injection by the pen-type syringe, the injection needle is removed from the pen-type cartridge and discarded as medical waste.

  Here, a diabetic patient may be in a state where only one hand can be used due to a cerebrovascular disorder, gangrene, a fracture due to a fall, paralysis on one side of the body, or the like. For such patients who can use only one hand, an auxiliary device for injecting insulin subcutaneously by the patient himself has been proposed.

  For example, Patent Literature 1 describes a pen-type syringe auxiliary tool as shown in FIG. That is, the pen-type syringe auxiliary tool 101 described in Patent Document 1 includes a needle case fixing device 104 that fixes the needle case 103 of the pen-type syringe 102 and a needle cap fixing device that fixes the needle cap 105 of the pen-type syringe 102. 106.

  As a method of using such a pen-type syringe auxiliary tool 101, first, the pen-type syringe auxiliary tool 101 is fixed to a desk, and the needle case 103 is installed in the needle case fixing device 104 of the pen-type syringe auxiliary tool 101. To do. Next, the pen type cartridge 107 is connected to the injection needle in the needle case 103. A series of methods is disclosed in which the pen cartridge 107 connected to the injection needle is removed from the needle case 103, and then the needle cap 105 is fixed to the needle cap fixing device 106 and the needle cap 105 is removed.

JP 2007-14615 A

  According to the above-mentioned Patent Document 1, even a patient who has difficulty with one hand, it is possible to connect an injection needle to a pen-type cartridge and to inject insulin subcutaneously by the patient himself / herself by a simple operation.

  By the way, since the injection needle is thin and long, when connecting the injection needle to the pen type cartridge, care must be taken so that the needle case with the pen type cartridge and the injection needle placed on the desk is parallel. If the injection needle is inserted obliquely even a little, a part of the injection needle hits the side surface of the pen-type cartridge, and the injection needle may be bent or broken. Therefore, when a doctor or the like explains to the patient how to use the pen-type injector, the instruction is always given to connect the pen-type cartridge straight to the injection needle.

  However, 10 to 20% of all diabetic patients have a tendency to decrease visual acuity such as blurred vision, and there is a possibility that the delicate work of the hand may be hindered due to fingertip tremor, sweating, and the like. Therefore, for a diabetic patient, it is very difficult to insert the injection needle straight into the pen type cartridge while keeping the pen type cartridge and the needle case in parallel.

  The present invention was devised in view of the above points, and provides a pen-type injector attachment aid that can accurately attach an injection needle to a pen-type cartridge regardless of who the situation is. It is intended to do.

  In order to achieve the above object, the pen-type syringe mounting aid of the present invention holds a pen-type cartridge having a rubber stopper through which a syringe needle can be inserted at the tip in a horizontally supported state so as to be movable in the horizontal direction. A pen-shaped cartridge holding portion, and an open end of a needle case including an injection needle that has a tapered shape from a rear end to an end, which is an open end, and a needle cap is attached to the inside of the pen-type cartridge. A needle case fixing portion capable of fixing the needle case so that the injection needle is positioned on a horizontal axis facing the rubber stopper and passing through an axis of the rubber stopper.

  Here, the pen-type cartridge is horizontally provided by including a pen-type cartridge holding portion that can hold the pen-type cartridge having a rubber stopper through which the injection needle can be inserted horizontally while being horizontally supported. It can be held so as to be movable in one direction while being supported. Accordingly, it is possible to easily translate the pen-type cartridge in one direction even in a patient having symptoms such as decreased visual acuity, trembling of fingertips, and sweating.

  In addition, the open end of the needle case including the injection needle, which is tapered from the rear end to the front end, which is the open end, and the needle cap is attached to the inside, faces the rubber plug of the pen type cartridge, By fixing the needle case so that the needle case can be fixed on the horizontal axis passing through the shaft center, the needle case is fixed with the side where the injection needle is exposed facing the pen-type cartridge. Can do.

  As described above, the needle case can be fixed with the side where the injection needle is exposed (open end side) facing the pen type cartridge, so when inserting the injection needle into the pen type cartridge, The injection needle can be inserted into the rubber stopper of the pen-type cartridge simply by translating toward the open end of the needle case. And since the needle case is being fixed to the needle case fixing | fixed part, a patient should just attach with the hand on the opposite side to the dominant hand which operates a pen type cartridge.

  At this time, the positional relationship between the needle case and the pen type cartridge is such that the injection needle integrated in the needle case is positioned on the horizontal axis passing through the axis of the rubber plug of the pen type cartridge. When translated in the direction, the needle is inevitably inserted in the center of the rubber stopper of the pen type cartridge. Therefore, even a patient who has symptoms such as decreased visual acuity, trembling of fingertips, and sweating, the injection needle can be inserted straight into the pen type cartridge. That is, when the injection needle is inserted into the rubber stopper, it is possible to prevent problems such as bending or breaking of the injection needle due to contact of the injection needle with a metal cap around the rubber stopper.

  In addition, the pen-type cartridge holding portion has a substantially cylindrical pen shape when a substantially U-shaped groove having a predetermined length and a predetermined depth extending along one direction is formed. With the cartridge inserted, it can be easily translated along the length direction (one direction) of the groove. At this time, since the groove has a substantially U-shaped cross section, there is no possibility of deviating from the groove when the pen cartridge is moved in parallel.

  Further, the needle case fixing portion can be fitted with a hook portion protruding outward from the periphery of the open end of the needle case, and extends in a direction substantially perpendicular to one direction, which is deeper than the concave groove. When a slit having a predetermined length is formed, the collar portion of the needle case can be fitted into the slit.

  At this time, since the slit is deeper than the first recess, the collar portion is inserted deeply into the slit, so that the slit can be more firmly fixed to the needle case fixing portion of the needle case.

  In addition, when the needle case holding part has a support part that supports the tip of the needle case, the tip of the needle case has a tapered shape, so when the collar part of the needle case is inserted into the slit, There is a possibility that the needle case will fall down to the tip side. Therefore, by having a support portion that supports the tip of the needle case, the needle case can be prevented from falling down and the needle case can be fixed in a more stable state. Therefore, it becomes possible to insert the injection needle straight into the pen type cartridge more reliably.

  The attachment aid for a pen-type injector according to the present invention can accurately attach an injection needle to a pen-type cartridge regardless of who is in any situation.

1 is a perspective view of a pen-type syringe mounting aid according to an embodiment of the present invention. It is a figure which shows the state which mounts a pen type cartridge and a needle case privately using the attachment auxiliary tool for pen type syringes concerning embodiment of this invention. It is a figure which shows a prior art.

  Hereinafter, embodiments of the present invention relating to a pen-type syringe mounting aid will be described with reference to the drawings to provide an understanding of the present invention. For convenience of explanation in each figure, in the state where the pen-type syringe mounting aid is installed on the installation surface, the upward direction from the installation surface of the pen-type syringe mounting aid is upward, and the opposite direction is the upward direction. An axial direction represented by a downward direction, an upward direction, and a downward direction is defined as a vertical direction, and an axial direction perpendicular to the vertical direction is defined as a horizontal direction.

  First, a pen-type syringe 2 used in the pen-type syringe mounting aid 1 according to the present invention will be described with reference to FIGS. 1 and 2. The pen type syringe 2 is mainly composed of a pen type cartridge 3, an injection needle 4, and a needle case 5.

  The pen-type cartridge 3 includes a cartridge 31 filled with insulin, which is a liquid medicine, a rubber plug 32 that is attached to the tip portion of the cartridge 31 and through which the injection needle 4 can penetrate, and a piston 33 that pushes out the insulin in the cartridge 31 to the outside. It is mainly composed of an injection button 34 for pushing out insulin after setting a dose to be pushed out by the piston 33.

  The amount of insulin pushed out by the piston 33 can be set by, for example, a dial (not shown) integrated with the injection button 34. Specifically, when the dial is rotated, a set insulin amount (unit) is displayed on a dial display unit (not shown). When the user sets the amount of insulin with the dial and then presses the injection button 34 at the rear end, the piston 33 pushes out the insulin in the cartridge 31 and ejects the insulin from the injection needle 4.

  A needle cap 41 is attached to the tip of the injection needle 4 for safety or hygiene, and is easily detachable from the injection needle 4. When a user injects insulin subcutaneously with the pen-type syringe 2, the user removes the needle cap 41 attached to the injection needle 4 and uses it.

  The needle case 5 further protects the injection needle 4 to which the needle cap 41 is attached, and the tip portion has a tapered shape corresponding to the shape of the injection needle 4, and the rear end side becomes the open end 51. ing. At the open end edge of the open end 51, a collar portion 52 that protrudes outward is provided.

  In the pen-type injector 2 configured as described above, when not in use, the injection needle 4 to which the needle cap 41 is attached is integrated with the needle case 5, and the pen-type cartridge 3 has a cap (not shown). Not stored) is stored.

  Next, the overall configuration of the pen-type syringe mounting aid 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  The pen-type syringe mounting aid 1 includes a pen-type cartridge holding portion 12 for holding a pen-type cartridge 3 and a needle for fixing a needle case 5 having an injection needle 4 with a needle cap 41 attached inside. The case fixing portion 13 is configured.

  The pen type cartridge holding part 12 has a substantially U-shaped concave groove on the upper surface of the base member 11 having a substantially square shape, which is aligned with the arc of the maximum diameter of the pen type cartridge 3. It is formed along the direction. In addition, the pen-type cartridge holding unit 12 can smoothly slide the pen-type cartridge 3 along the length direction of the concave groove in a state where the pen-type cartridge 3 is inserted into the concave groove.

  Here, the pen-type cartridge holding part 12 does not necessarily have a configuration in which a concave groove having a substantially U-shaped cross section is formed along one direction. The pen type cartridge holding unit 12 may be in any form as long as it can move in parallel along one direction (the length direction of the pen type cartridge 3) while holding the pen type cartridge 3. For example, a plurality of ribs formed with through-holes through which the pen-type cartridge 3 can pass are installed along the parallel movement direction of the pen-type cartridge 3, and the pen-type cartridge 3 is translated while being inserted through the through-holes of the ribs. The structure to be made may be sufficient.

  However, when the pen-type cartridge holding part 12 is constituted by a groove having a substantially U-shaped cross section, no additional parts are required, and the pen-type cartridge 3 can be installed in the pen-type cartridge holding part 12. It is easy and the slide movement can be performed smoothly. Therefore, from the viewpoint of economy and operability, the pen type cartridge holder 12 is preferably configured according to the embodiment of the present invention.

  The needle case fixing portion 13 is recessed in the base member 11 so as to be connected to the pen type cartridge holding portion 12 in accordance with the shape of the needle case 5. Specifically, it is mainly composed of a slit 13a into which the collar portion 52 of the needle case 5 can be inserted and a support portion 13b for supporting the tip portion of the needle case 5 and maintaining the needle case 5 in a horizontal state. Has been.

  The slit 13 a is connected to the pen type cartridge holding part 12 and is formed in a direction substantially orthogonal to the length direction of the concave groove of the pen type cartridge holding part 12. The depth of the slit 13 a is formed slightly deeper than the depth of the concave groove of the pen type cartridge holding portion 12, and specifically, is set to be substantially the same as the height of the collar portion 52 of the needle case 5. Therefore, the movement of the needle case 5 in the horizontal direction is restricted in a state where the collar portion 52 of the needle case 5 is inserted into the slit 13a.

  Here, the depth of the slit 13a does not necessarily have to be substantially the same as the height of the collar portion 52 of the needle case 5, and may be set shallower than the height of the collar portion 52 of the needle case 5. However, when the depth of the slit 13a is shallower than the height of the collar portion 52 of the needle case 5, the fixing of the needle case 5 at the needle case fixing portion 13 becomes unstable, and thus the needle case 5 is stably fixed. From this point of view, it is preferable that the height of the flange portion 52 and the depth of the slit 13a substantially coincide.

  The support portion 13b supports the distal end portion of the needle case 5, and prevents the needle case 5 from falling to the distal end side in a state where the collar portion 52 is fitted into the slit 13a. The whole is maintained in a horizontal state. The support portion 13b is formed in a mountain shape having the apex at the position where the tip portion of the needle case 5 abuts in the state where the needle case 5 is fitted into the slit 13a.

  Here, the support portion 13b does not necessarily have a mountain shape, and any shape can be used as long as the needle case 5 can maintain a horizontal state in a state where the collar portion 52 of the needle case 5 is fitted into the slit 13a. It may be a simple shape. For example, a protrusion that can contact the tip of the needle case 5 may be provided on the base member 11.

  Next, a procedure for attaching the injection needle 4 to the pen-type cartridge 3 using the pen-type injector attachment aid 1 configured as described above will be described.

  First, the user inserts the collar portion 52 of the needle case 5 in which the injection needle 4 attached by the needle cap 41 is integrated into the slit 13 a of the needle case fixing portion 13 to support the tip of the needle case 5. It is supported by the part 13b. At this time, it is preferable to visually confirm whether the horizontal state of the needle case 5 is maintained.

  Subsequently, the pen cartridge 3 filled with insulin is placed on the pen cartridge holder 12. At this time, it is possible to visually confirm that the injection needle 4 exposed through the open end 51 of the needle case 5 is positioned on an extension line of an imaginary straight line passing through the axis of the rubber plug 32 attached to the tip of the cartridge 31. preferable.

  When the horizontal state of the needle case 5 and the pen type cartridge 3 can be confirmed, for example, the needle case 5 is attached with one hand to restrict the movement, and the pen type cartridge 3 is lightly grasped with the other hand. In this state, the pen type cartridge 3 is slid along the concave groove of the pen type cartridge holding portion 12 toward the open end 51 of the needle case 5.

  When it is confirmed that the injection needle 4 has penetrated the rubber plug 32 of the pen type cartridge 3, the pen type syringe 2 in which the needle case 5 and the pen type cartridge 3 are integrated is removed from the pen type syringe mounting aid 1, and further The needle case 5 and the needle cap 41 are removed.

  Through the above steps, the setting of the pen-type syringe 2 is completed, the user injects the injection needle 4 toward the affected part, and the insulin injection operation is completed.

  As described above, the pen-type syringe attachment assisting tool according to the present invention can accurately attach the injection needle to the pen-type cartridge regardless of who is in any situation.
